Belt known that we, AMEDEE DIoN AND BRUNO DIoN, Brltish 81113160138, farmers, re-

siding at Ste. Therese de Blainville, in the I Province of Quebec, in the Dominion of Canada, havelnvented certain new and useful Improvements 1n Band-Cutters and F eeders; and we do hereby declare that the following is a full, clear, and exact description of the same.

The present invention-relates to band cutters and feeders for threshingmachines and.

is an improvement on United States Patent No. 1,345,588, dated July 6th, 1920, and its main object is to provide an improved mechanism for feeding grain evenly to the thresher; for cutting the bands; and for spreading the grain before itreaches the cylinder.

The invention will be better understood 2 with the aid of the accompanying drawings Which form part of the application andin which v n i 7 Figure 1 is a longitudinal side elevation of the machine, from one side thereof.

Fig. 2 is a longitudinal side elevation of the machine, one of the sides having been removed.

Fig. 3 is an end view of the machine, the casing being broken away.

Fig. 4 is a longitudinal side elevation-of the machine from the other side.

,Fig. 5 is an enlarged perspective detail Fig. 6 is a detail perspective view of therctard ng spiral members and its supporting means;

Like numerals of reference indicate corresponding parts in each figure. f

In the drawings, 1 indicates a feeder frame, and 2 are the side plates of the frame which are connected by suitable cross bars so as to form an open frame. .A'pulley 3 is mounted at one end of themultiple crankshaft 4 which is suitablyjournaled in the side plates 2 of the frame, said pulley being 1 adapted to be connected by means of a belt (not disclosed in the drawings) to any source of power. 3

5 arelongitudinal feeding bars provided with a plurality of depending cutting teeth 6. said feeding bars being connected inter} mediate of their length to the multiple crank- 4, and reciprocated simultaneously thereb said bars, being connected at their rear en s Specification of Letters Patent. Patented ltlay 10, 19 21. Application filed August 21, 19 20. sefiafNo. 405,066.

by the pivoted links 7 mountedon the cross shaft 8 journaled-in the frame. cross, shaft '8, on the exterior side of the frame, a lever member 9. is mounted, and 10 is a connectingrod projecting diagonally and' at its lower end adapted to engage a crank-lever 11 which oscillates the pivoted pan 12 mounted below frame -1.

A feeding conveyer or carrier 13 is provided in said frame 1, consisting of an endless belt 14 andactuated by the sprockets 15 On said .andichain 16, twoiof said sprockets 15 being with the sprocket 25 mounted on the shaft 19. A tension pulley 25 is mounted inter mediate of said chain drive 24?.

26 are circular members or drums 'movably supported on the pivotal circular U- ated by the chain drive 24 "which co-acts shape members 27, each being connected by i a tubular portion 28 adapted to engage and be supported by said shaft 23, and 29 is a horizontal projecting arm having thereon a vertical'pin; 30. On said drums 26 is loosely .mounted the gear 31, said gear being provided on its outer periphery with a plurality of triangular teeth or cutting blades 32, which act to sever the bands on the bundles during the passage of the latter beneath,

and to cooperate with the teeth 6 in cutting the bundles before they reach the cylinder.

133 are pinions mounted on the shaft 23 en'- gaging said gears 31 and adapted to rotate the same. The said gears 31 must be large j enough in diameter so as to encircle the crank-shaft 4, and said drums are so supported. on said semi-circular U shape members, as to be oscillated or rocked to and fro by the passage beneath it of a bundle cross- I led to the semi-circular U-shape members 27, tubular extension28, arm 29,,which in turn will operate the arm 34slidably mounted on the vertical rod 35 which is pivotallyconnected at its lower end, on the exterior side wise, the. rocking movement being impart- V i spiral spring 87 is mounted onthe-pin 3O and onthe upper end of the rod 35, so as to 1 provide a bu'fler,in case the machine was I I being spring-held by means of the flat spring 70.- .On one end of said angularly bent bar chocked by a too large amount of straw.

The stop-member 36 is preferably. pivotally mounted at 38, and is adapted '.to engage the pawl 39. A gear 41' mounted onthe shaft 17 "co-acts with the pinion 42 mounted on the shaft 19.

The pawl 39 is pivotally supported mejans' of. the carrier 45' which is rigidly gear 41,- a sprocket gear 47 connected to the ear, 48' by'm'eans of'the chain 49 ,.s a1'd; gear 48 being mounted on the suspended cross sliaft49 whichis suitably j ournaled to the slightly movable or swinging bearings 50'.

The said shaft 4.9 projects" through holes 51 provided in the sides of'the frame 1." The bearings 50 are mounted on the perpendicular rods 51 and are secured to'the shaft 52,

mountedonl the brackets 53, securedin the upper portion of said frame 1.' said shaft 49 are rigidly mounted, at suitable intervals, the retarding spiral members 54.

Adjacent one of said bearings is pro vided astop member55 consisting of an outwardly extending portion '56, having at {right angle thereto one arm 57 to" whichis rigidly secured the stop-arm 58 which ex.

tendslongitudinally in relation to the frame 1 and isadapted to.contac t with the pawl 39. At the other-end of said extending porwardly' on said Shea 49 tion 56jis provided a downwardly'prdjecting ortion-59 which is provided with an oblong not some w lls of which are adape ed'to' engage said shaft 49*, so that it may i ,be carried with said shaft. If a too largeamount of straw-comes to pass the retarding' spiral memb'ers'54, the shaft 49 will'be swung slightly 'inwardly carrying with it and thus tipping the stop-member 55', and the stop-arm 58, so that it will contact with ipa 3'9, to interrupt th r t ti of said shaft 17, I

A .61 is secured to said outwardly extendingpfirtion 56 a one e and. at its other end tojthe frame 11, so as to'release .saidstOp-arm 58 from thepawl 39, while a flat sp'ring61 is provided to press down- The perendicular rods 51* are. carried to; their normal positionf by means of'the his-mantel springqheldrods62, which projectfthrough a bracket 63, secured to'the" frame 1.;

1, is slidably'mounted on the crank-shaft 4 adisk 64 which is provided on one face.

thereof, with a laterally projecting spiral cam adapted toengage the angularly bent bar 65 ful'crumed at 66in the forked end 66*- of th oblique rod 67 projecting adjacent the pawl 68 mounted in the carrier 69, which is mounted on the shaft 19, the said carrier 65 is mounted a roller 71 adapted to contact with" the spira-l-camon" the disk 64, and 72 is a spring tension or resilient means pr'ovided between said bar 65 and said rod 67 gage the spiral cam on the disk 64, but when the speed is reduced, the centrifugal governor 78 will force said disk away from the gear21, thereby bringing the cam onsaid diskv into position to engage said bar 65. The rod 67 will be tilted by the said bar 65 and its face end loweredslightly, as illustrated in Fig. 4 of the drawings, inwhich position it will engage the pawl 68 and stop the gear 18', with the result that the conveyer 13, and the retarding spiral members 54 will be stopped:
